What are the main classifications of refractory materials produced by brick mills?

There are many types of refractory materials. Next, I will introduce some types of refractory materials.

Ordinary refractory
Common refractory materials include silicon brick, semi-silica brick, clay brick, high alumina brick, perlite, magnesium brick, etc.
Special materials include AZS bricks, corundum bricks, direct bonded magnesia-chrome bricks, silicon carbide bricks, silicon nitride bonded silicon carbide bricks, nitrides, silicides, sulfides, borides, carbides and other non-oxide refractory materials; calcium oxide , Chromium oxide, aluminum oxide, magnesium oxide, beryllium oxide and other refractory materials.

Insulation refractory
Insulation and refractory materials mainly include diatomite products, asbestos products, insulation boards, etc.

Unshaped refractories
Unshaped refractory materials include refuelling materials, refractory ramming materials, refractory castables, refractory plastics, refractory mud, refractory spray repair materials, refractory projection materials, refractory coatings, lightweight refractory castables, gun mud, etc.

Refractories
1. High-aluminum products 2. Mullite products 3. Clay products 4. Siliceous products 5. Magnesium products 6. Carbon-containing products 7. Zirconium-containing products 8. Thermal insulation products

What are the physical properties of refractory materials?
The physical properties of refractories include structural properties, thermal properties, mechanical properties, use properties and workability. The structural properties of refractories include porosity, bulk density, water absorption, air permeability, and pore size distribution.

Thermal properties of refractory materials include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal conductivity coefficient, thermal emissivity. Mechanical properties of refractory materials include compressive strength, tensile strength, flexural strength, torsional strength, shear Strength, impact strength, abrasion resistance, creep, bond strength, elastic modulus, etc.

The use properties of refractory materials include fire resistance, load softening temperature, reburning line change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, hydration resistance, CO erosion resistance, electrical conductivity, and oxidation resistance Wait. The workability of refractory materials includes consistency, slump, fluidity, plasticity, cohesiveness, resilience, coagulation, and hardenability.
